To all whom it may concern,.- V

Be it known that I, WILLIAM A. FAGAN, a subject of'Great Britain,residing in thecity and county of San Francisco, State of California,have invented certain new and useful Improvements inDoor-Releasers; andI do hereby.. declare the following to be a full, clear,`and exactdescription 'of the same.

`The present invention is designed foruse in connection' with flats orapartmenthhouses or houses wherein it is desired to release the lock--catch of the front vdoor or outer door from aV distant point, theiobject being to provide against the necessity of having to travel from adistant pointor to descendthe stairs for the purpose of releasing theouter door in order that the-same may b e opened' for a person'desiringadmission, the invention residing in the meanswhereby thedoor-catchisjmechanically released and the door slightly-opened from a distantpoint through the mediumof a system of crank-levers and wireconnections..`

To comprehend vtheJl invention, reference should be had tothe drawings,wherein-y `Figure 41` is an inside view'of a'n ordinary door, theldoor-casing being partly broken away and sectioned in order toillustrate the location of the releasing device and the opener,

together with the connections for the opera. tion yofl said'devices.tional end' view of the casing, illustrating'the position of thereleaser and the opener. Fig.`

8 is an enlarged broken. detail view of the door, the `casing lbeing invertical section. Fig. 4 is an enlarged detail view ofthe releaserviewed from the opposite side from that disclosed by Fig.3 of thedrawings, and'Fig. 5

the opening device for the door. The numeral 1 designates an ordinaryou'te door for ahouse, and 2 the casing therefor, to

which the door is hinged.

Within the side 2 of the casing is fulcrumed is an enlarged detail viewin end elevation of the lever`3, which is connected to the 4ful--accompanying.` sheet of.

Fig. 2 is a vertical sec spectively, tothe pillars 4' 6". The oppositearm of thecrank-lever 6 is'fconnectedby wire 8 to one Aend of thelongitudinally-movable re- .leasing-bolt 7', which bolt works throughthe catch-opening of the lock-plate 8', fitted within the side' 'of thelcasing 2, Figs. 1,5 3, and 4 of the drawings'. Y The releasing-bolt 7'is held in place by means of the screw-stud 82, which studpasses througha slot 9 cutin the said bolt and screws into the lock-plate 8'. TheAlockplate 8' is formed with an inclined shoulder 9',

upon which `bears and rides a roll 10, secured to one face of theslide-releasing bolt-7', Figs. 3 and 4 of the drawings. The louter or--free end of the releasing-bolt 7', when the door 1 is closed, bearsagainst the door-catch 10'. By this construction it is obvious that asthe inner end of the vslide-bolt 7' is drawn upward the roll 10 workingupon -the face-of the inclined shoulder 9 will force the said slide-boltoutward atan inclination. -As thusk moved the pressure of thereleasing-bolt against the door-catch 10' will'forcethe catch outwardbeyond the catch-opening of the lock-plate 8' or back into the lclr,thus releasing the locked door and leaving same free to be opened bypulling upon the door-knob 11.' "So long as the upward or pulling straincontinues on the wire 8 to maintain the releasing-bolt moved outward thedoor will be held releasedj It will be understood that the stud 82 actsas the fulcrum for the slide-releasing bolt 7'.

To. indicate that the door'is'rel'eased, an`

opener is provided which Will force outward the doora slight distancethe moment the locke' catch has been released. lhis'deviceis operatedmechanically by they movement of the releasing-boltwand is soconstructed as to remove all` strain from thefloor when closed.'y Theopening device is located within the side '3' of the door-casing, nearthe bottom thereof,

swings tranverse of the casing, the roll 14'` IOO carried therebyworking within a transverse slot l15 cut in the face of the plate 13.yThe projecting end of this roll when the crank-lever is inward its fulldistance fits within a socket or recess 15' cut in the rabbet 16 ofthedoor-casing. Said roll rests against a bearingplate 16, secured to theedge of the door, so that the pressure of the roll upon the door duringthe opening thereof will not injure the surface of the woodwork.

The described device is actuated to open the door as the door-catch isreleased by the upward pulling strain exerted upon the wire 17, formingconnection between the releasingbolt 7 and the bell-crank lever 12,acting to swing the crank -lever 12 outward transversely, causing theprojecting roll 14', bearing against the edge of the door, to graduallyforce the door open a slight distance as the roll is thrown outwardwithin the slot 15 of the plate 13. As the pulling strain which actuatesto operate the releasing-bolt ceases the tension of the'spring 13 forcesthe crank-lever 12 inward or in a reverse direction, so as to restorethe same to its normal or closed position. eXerts'a downward pull uponthe wire 17 in order to draw the releasing-bolt 7 inward or restore itto its normal position. At the same time the tension of the spring 17',which forms a connection between the crank 6 and the doorcasing, Figs. 1and 2 of the drawings, restores thelever 3 and cranks 4 and 6 and theirconnections to normal position. When the parts are thus restored totheir normal positionrthe door 1 is free to be closed, which may be doneautomatically or otherwise. In the present case an ordinary pneumaticdoor-closer 18 is employed to close the door. However, the feature ofclosing the door forms n0 portion of the present invention. Hence noconsideration need be given thereto.

The described mechanism for releasing the door-catch and opening thedoor is operated by means of the wire 18. One end of this wire isattached to the lever 3, Fig. 1 of the drawings, its opposite endterminating at whatever distant point from which itis desired to operatethe releasing and opening mechanism. This wire 18 for the purpose of thepresent case shall be termed the main house-wire, meaning thereby thewire to be actuated from any fixed distant point within the house by theperson desiring to operate the mechanism to release and open the door.

Having thus described the invention, what is claimed as new, and desiredto be protected byLetters Patent, is-

1. The combination -with a door, of an inwardly-movable slide-'bolt foractuating the lock-catch thereof to release the door, devices forcausing the slide-bolt to travel at aninclination to the lock-catch ofthe door, a transverselymovable device for partly opening the door soreleased, connection between the This movement of the crank-lever 12releasing slide-bolt and the opening device by which the opener ispositively actuated with the movement of the releasing slidebolt torelease the lock-catch, and connections between the releasing slide-boltand a distant point for operating the said slide-bolt and its connecteddevice to release the door and open the same.

2. A door releasing and opening mechanism, the same comprising alongitudinally-movable releasingbolt for acting against the lockcatch ofthe door, devices for causing the rcleasing-bolt to travel at aninclination during longitudinal movement thereof to release thelock-catch, a transversely-movable device for opening the door whenreleased, connection between the releasing-bolt and the opening devicefor the door so that the releaser and opener operate substantiallysimultaneously, a house-wire actuated from a distant point, connectionbetween the house-wire and the releasing-bolt, and means for restoringthe parts to their-normal position when the housewire is released.

3. Adoor releasing and opening mechanism, the same consisting of alongitudinally -movable releasing-bolt, devices for causing the same totravel at an inclination during the longitudinal movement thereof, ahouse-wire operated from a distant point, connection between the saidwire and the releasing-bolt, and means for restoring the parts to theirnormal position when the house-wire is released.

4. In a releaser for doors, the combination with the door-casing, alock-catch plate fitted therein, a releasing-bolt slidably connected tosaid plate, a roll carried by the bolt, an ineline surface on the plateupon which the roll of the bolt works to move the same outward, ahouse-wire, connections between said wire and the releasing-bolt, andmeans for restoring the parts to their normal position when thehousewire is released.

5. In a releaser and opener for doors` the combination with the doorcasing, a lockcatch plate iitted therein, a releasing-bolt slidablyconnected to said plate, a roll carried by the bolt, an inclined surfaceon the plate upon which the roll of the bolt works to move the sameoutward, a transverse]y-movable device for opening the door when itslock-catch is released, said device bearing against the door whenclosed, connection between the opening device and the releasing-bolt, ahouse-wire, connections between the house-wire and the releasing-bolt,Vand means for restoring the parts to their normal position when thehousewire is released'.

In witness whereof I have hereunto set my hand.
